Summary: random exim_setugid / getpwuid bug
Product: Exim
Version: 4.69
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: bug
Priority: high
Component: Delivery in general
AssignedTo: nigel@???
ReportedBy: dominic.germain@???
CC: exim-dev@???
The "exim_setugid" (exim.c) function randomly exit with "cannot run
initgroups(): no passwd entry for uid=90".
It happend when then "deliver_message" function (deliver.c) is trying to
generate a bounce after failing delivering a message to a remote host.
So, the undeliverable message get frozen and remain in the queue until a
successful bounce retry. I also got a "Process failed (1) when writing error
message" in message_log because of the child that crash being unable to run
exim_setugid.
It seems that "getpwuid" which is involve in "exim_setugid" is sometime
returning NULL instead of the logged user.
For a 12 hours period, it could happend 5 to 10 times.
I got that problem on 2 Xserves Intel/10.5.4. I never got that on 3 Xserves
PPC/10.4.1. All of them are compiled the the same way using "exim" as
exim_user and "staff" as exim_group.
