[rt-users] RT 4.2.3 - Intermittant Mail Failures with rt-mailtool

[Lee Wilson]

Thanks Alex,

The /opt/rt4/var directory is definitely writable by www-data as are all the sub-directories.

File systems look good, plenty of disk space and all have no more than 20% inode utilisation so even if there an odd spike it should have enough space.

Oddly, I've restarted the device tonight as I've done every other night (only a dev box so isn't on all the time) and since then it's no longer erroring so guess I'll just have to keep an eye on it.

The error comes from the server, not rt-mailgate.  Also, by default, RT
writes its tmpfiles to /opt/rt4/var, not /tmp -- check that the former
is writable by your webserver.

The error comes from deep within the core tmpfile-handling module that
Perl provides.  I suspect it is caused by running out of inodes, too
many subdirectories of /tmp, or something similar filesystem-related.
