Hi list!

I just upgraded from earlier (from about 1-2 years) sqwebmail to 0.53.2-3 debian version.

I have a problem with the new version. Unknown sqwebmail event triggers that I think it runs into endless cycle.

my ps auxf shows: --- USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND 119 31792 3.7 29.7 433900 267472 ? D 00:53 28:33 /usr/lib/courier/courier/sqwebmaild 119 31818 0.0 0.0 3152 532 ?

I don't known sqwebmail internals. I don't see any warning in syslog. The 119 user is exim4. I think the problem is with these processes and it's call of gzip. I upgraded together the kernel of the system from 2.6.8.1 to 2.7.17.11 with grsec. The system is smp if it matters.
