[debian-mysql] Bug#501273: libmysqlclient15off: libmysqlclient.so.15.0.0 segfault

[Emmanuel Lacour]

Package: libmysqlclient15off
Version: 5.0.51a-12
Severity: important



Hi,

using RT 3.8.1 (and so DBD::mysql) as fastcgi process on lenny, I have
some times (mornings) this error in syslog:

kernel: [629096.801411] mason_handler.f[25833]: segfault at 8 ip 7fd3dd296afa sp 7fffe8ede7d0 error 4 in libmysqlclient.so.15.0.0[7fd3dd23e000+1bf000]

and trying to connect to RT give of course an internal server error.

I saw some bugs related in libdbd-mysql-perl, so I also tried
libdbd-mysql-perl_4.008-1 instead of the current
libdbd-mysql-perl_4.007-1 in Lenny, with no success.

This segfault makes me think that this is a pure mysql bug.

Apache error log give no more informations:

[warn] FastCGI: server "/opt/rt/rt/bin/mason_handler.fcgi" (pid 25733) terminated due to uncaught signal '11' (Segmentation fault)


Error seems to appear after daily logrotate (so trigered by apache or mysql
restart I think).

thanks for any help...
