It’s a fairly vanilla install of nginx (with the exception of the SPDY patch). We are seeing roughly 1 segfault every hour or so on each web server… I didn’t generate a debugging log, because I wasn’t sure how big something like that would be for an entire hour, but I can if needed. * * * ## nginx -V nginx version: nginx/1.3.12 built by gcc 4.5.1 20101208 [gcc-4\_5-branch revision 167585] (SUSE Linux) TLS SNI support enabled configure arguments: --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx –pid-path=/var/run/nginx.pid --error-log-path=/usr/log/ngnix/error.log –http-log-path=/usr/log/ngnix/access.log –with-openssl=/home/software\_source/openssl-1.0.1c --with-cc-opt=‘-I /usr/local/ssl/include’ --with-ld-opt=‘-L /usr/local/ssl/lib’ –without-http\_proxy\_module --without-http\_ssi\_module –with-http\_ssl\_module –with-http\_stub\_status\_module --with-http\_spdy\_module * * * ## backtrace from core dump: # #0 0x00000000004514ea in ngx\_http\_spdy\_send\_output\_queue (sc=0xd77610) at src/http/ngx\_http\_spdy.c:713 cl = c = 0x7fe9a5436f90 clcf = out = frame = 0xa250d0 fn = #1 0x00000000004520b2 in ngx\_http\_spdy\_write\_handler (wev=) at src/http/ngx\_http\_spdy.c:644 rc = c = fc = ctx = r = stream = s = sn = sc = 0xd77610 #2 0x000000000041a5ba in ngx\_event\_process\_posted (cycle=, posted=0x854a88) at src/event/ngx\_event\_posted.c:40 ev = #3 0x000000000041a1d5 in ngx\_process\_events\_and\_timers (cycle=0x885a90) at src/event/ngx\_event.c:276 flags = 3 timer = delta = 81 #4 0x0000000000420038 in ngx\_worker\_process\_cycle (cycle=0x885a90, data=) at src/os/unix/ngx\_process\_cycle.c:807 worker = i = c = #5 0x000000000041e9a3 in ngx\_spawn\_process (cycle=0x885a90, proc=0x41ff6c \, data=0x2, name=0x59b51a “worker process”, respawn=-3) at src/os/unix/ngx\_process.c:198 on = 1 pid = 0 s = 2 #6 0x000000000041f5f6 in ngx\_start\_worker\_processes (cycle=0x885a90, n=4, type=-3) at src/os/unix/ngx\_process\_cycle.c:362 i = ch = {command = 1, pid = 6348, slot = 1, fd = 19} #7 0x00000000004206d1 in ngx\_master\_process\_cycle (cycle=0x885a90) at src/os/unix/ngx\_process\_cycle.c:136 title = 0x973f74 “master process /usr/sbin/nginx” p = size = 31 i = 1 n = sigio = set = {\_\_val = {0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0}} itv = {it\_interval = {tv\_sec = 0, tv\_usec = 0}, it\_value = {tv\_sec = 0, tv\_usec = 0}} live = delay = ls = ccf = 0x0 #8 0x000000000040546c in main (argc=, argv=) at src/core/nginx.c:412 i = log = 0x84d7a0 cycle = 0x0 init\_cycle = {conf\_ctx = 0x0, pool = 0x884fa0, log = 0x84d7a0, new\_log = {log\_level = 0, file = 0x0, connection = 0, handler = 0, data 0x0, action = 0x0}, files = 0x1, free\_connections = 0x0, free\_connection\_n = 0, reusable\_connections\_queue = { prev = 0x0, next = 0x0}, listening = {elts = 0x0, nelts = 0, size = 0, nalloc = 0, pool = 0x0}, paths = {elts = 0x0, nelts = 0, size = 0, nalloc = 1, pool = 0x0}, open\_files = {last = 0x0, part = {elts = 0x0, nelts = 0, next = 0x0}, size = 0, nalloc = 0, pool = 0x0}, shared\_memory = {last = 0x0, part = {elts = 0x0, nelts = 0, next = 0x0}, size = 1, nalloc = 0, pool = 0x0}, connection\_n = 0, files\_n = 0, connections = 0x0, read\_events = 0x0, write\_events = 0x0, old\_cycle = 0x0, conf\_file = { len = 0, data = 0x0}, conf\_param = {len = 0, data = 0x0}, conf\_prefix = {len = 1, data = 0x0}, prefix = {len = 0, data = 0x0}, lock\_file = {len = 0, data = 0x0}, hostname = {len = 0, data = 0x0}} ccf = Posted at Nginx Forum: > **[1.3.12 occasional segfaults](https://forum.nginx.org/read.php?2,236409,236409#msg-236409)** > > It's a fairly vanilla install of nginx (with the exception of the SPDY patch).

First of all, please update nginx and spdy-patch to the latest versions: [http://nginx.org/download/nginx-1.3.13.tar.gz](http://nginx.org/download/nginx-1.3.13.tar.gz) [http://nginx.org/patches/spdy/patch.spdy-65\_1.3.13.txt](http://nginx.org/patches/spdy/patch.spdy-65_1.3.13.txt) It is possible that the problem is already solved. wbr, Valentin V.

Yeah sorry… I didn’t see 1.3.13 came out the day prior. Either way, glad whatever it was seems to have been fixed before I asked… Upgrading to 1.3.13 and the occasional segfaults stopped.
