Hello

Thank you all for response.

Actually problem we see is related with our server running 117350-41
kernel. SUN recommend to fix this by applying patch 117350-45. From
description of bug fixed with this patch I understood that bug was
introduced with patch 117350-38. 117350-45 is release to fix specific
problems related with proftp:

BUG ID 6476945: System unable to reboot properly after proftp ftp
session.

In thread http://bugs.proftpd.org/show_bug.cgi?id=2336 there is stated,
that problem is related with bug "4817079 open/close of /dev/log leaks
kernel memory".

But this bug was fixed in 117350-02.... So what? SUN reintroduced same
bug with -38 and fixed again in -45?....

I also want make others aware about possible problems with syslog
service in kernel revisions from -38 till -44.

With best regards
Martynas

That's the theory. However, Sun has in no way ever communicated
anything
of the sort to the ProFTPD Project to indicate an issue with proftpd's
usage of system calls. Thus there's no way of us to know anything about
the issue, much less correct it.

Perhaps Sun's issue is referring to this:

http://bugs.proftpd.org/show_bug.cgi?id=2336

In that particular instance, I had to actively approach Sun in order to
find the root the problem; Sun was not helpfuly in any way, shape, or
form
as a business entity.
