Package: exim
Version: 3.35-1woody2
Severity: important
Tags: patch
Exim produces a lot of messages. I.e.:
Nov 25 13:35:12 szafir kernel: application bug: exim(24490) has SIGCHLD
set to SIG_IGN but calls wa
it().
Nov 25 13:35:13 szafir kernel: (see the NOTES section of 'man 2 wait').
Workaround activated.
Nov 25 13:36:15 szafir kernel: application bug: exim(25506) has SIGCHLD
set to SIG_IGN but calls wa
it().
Nov 25 13:36:15 szafir kernel: (see the NOTES section of 'man 2 wait').
Workaround activated.
This is because exim sets SIG_IGN on SIGCHLD signal and this is error
for Linux kernel.
The attached patch tries to fix the bug.
