I have script which I run three times a day, it does heavily threaded
SNMP polls and populates SQL table.
I’ve ran it couple years now, and twice it has hanged and had to be
‘kill -9’ to recover, ‘kill -1’ did not recover. And I can’t figure
out why it is hanging. When I truss the PID I get:
SIGNAL 26 (SIGVTALRM)
sigreturn(0xbfbfe6b0,0x1a,0x0,0xbfbfe6b0,0x0,0x280a78b0) = 1 (0x1)
In a loop, and very very rarely I see:
SIGNAL 26 (SIGVTALRM)
sigreturn(0xbfbfe6b0,0x1a,0x0,0xbfbfe6b0,0x0,0x280a78b0) ERR#1
‘Operation not permitted’
I can provide script, if it’ll help determine the problem. But I’d
rather provide it unicasted, if it isn’t too much trouble.
Thanks,
