Hi,
I've fixed the below (previous post) which was simply a case of
reading the monit manual (it nukes most of the environment settings
when it runs the script).
Now I'm in a position to debug my problem, which is (I think)
image_science crashing mongrel during processing of an uploaded file
with a message of: terminate called after throwing an instance of
'int'.
I'm finding it difficult to reproduce the crash reliably as uploading
the same file works sometimes and not others. I've tried running
mongrel with -B, and using killall -USR1 but nothing out of the
ordinary is being reported.
I've also tried strace-ing the mongrel process and this snippet is the
closest I can get to something useful:
open("/tmp/rpupload6375.0", O_RDONLY) = 12 <0.000113>
futex(0xb6179e2c, FUTEX_WAKE, 2147483647) = 0 <0.000088>
futex(0xb60a41a4, FUTEX_WAKE, 2147483647) = 0 <0.000081>
write(2, "terminate called after throwing an instance of \'", 48) = 48
<0.000137>
write(2, "int", 3) = 3 <0.000092>
write(2, "\'\n", 2) = 2 <0.000091>
rt_sigprocmask(SIG_UNBLOCK, [ABRT], NULL, 8) = 0 <0.000146>
tgkill(6375, 6375, SIGABRT) = 0 <0.000083>
--- SIGABRT (Aborted) @ 0 (0) ---
Is it perhaps some sort of file locking issue? Any ideas on how I
could go about better tracking down the problem?
Thanks,
- Paul
