I have seen problems with imtest when file descriptor ulimit was set to unlimited. imtest would dump right after a successfull authentication. This may be your problem when setting quota with cyradm. Try to set the file descriptor limit to your hard limit (1024) and try cyradm again. > I played around with using skiplist for quota_db last night, but > couldn't get it to work, setting/getting quotas just hung (cyradm). > After I moved back to quotalegacy and copied back the previous quota > files, I haven't seen the System I/O errors to "Too many files" message > since, however, if it is a descriptor leak as Ken suggested, it may take > a while to show itself. > > I ran pmap and pfiles against an imapd and lmptd process.

I though I saw that that 256 was a 32-bit app limit (at least on > Solaris), but I'm not sure. The cyrus code is currently all compiled at > 32-bit, not 64-bit. This is fine, cyrus (master) sets unlimited rlimit for itself and 256 for each service. > Are your running version 2.2.5 or an earlier version (like 2.2.3) of > imap?
