Comment 187 for bug 36581

me too.
gamin-0.1.1-4.EL4
thunderbird-1.5.0.10-0.1.el4.centos
kernel-2.6.9-42.0.8.EL

i used to see this alot on a prior system running courier-imap. running dovecot
on this one. wasn't seeing the gam_server hang much recently until recent yum
update when among others thunderbird upgraded (to above) from
thunderbird-1.5.0.9. now i frequently find gam_server eating all available CPU.
 kill it, and it immediately gets respawned. kill thunderbird, and gam_server
quiets down. relaunch thunderbird and things are fine again for a couple days.
 if you want more info let me know what would be helpful.
