I have a program to generate my website bluebottleimages.org
It creates thumbnails using Rmagick. I run the program (on the server),
and it goes for a while, but then I get
RMagick: UnableToConcatenateString `
Warning: recursive semaphore lock detected!
and it’s stopped there.
It has come up invariably at the same spot, so I thought it was
corrupted image files, but even after replacing them I get the error
message. Now I’m thinking that it’s probably just that I’m over-using
server resources making all those thumbnails… Do you think that’s
the case, or is it more likely that there’s a problem with my program?
If you like I can post my code.
