Every so often, and seemingly randomly, I see this error in
/var/log/messages just as the FCGI server stops working:
Oct 25 13:43:07 RTServer RT:  Argument “username” isn’t numeric in
numeric ne (!=) at /opt/rt4/sbin/…/lib/RT/Interface/Web.pm line 3027.
It shows up three times, at the same exact time, and that’s it. The
"username" appears to be the username of one of our users (I’ve replaced
the actual name with ‘username’ for this email). This is the only reason RT
ever goes down. If it weren’t for this, I doubt we’d have any problems at
all. Manually restarting the FCGI server fixes things for anywhere from one
to five days before the same problem happens again. Has anyone seen this
before? RT4.4.1 on Debian 8. Thanks.
