Symptoms
After updating to cPanel 132, the following error is logged in /var/log/messages when restarting Dovecot:
Dec 10 09:21:48 10-2-32-109 kernel: auth[2707524]: segfault at 7f48b49767f3 ip 00007f48b528f91c sp 00007ffe43abafb8 error 4 in libc-2.28.so[7f48b51d3000+1cd000]
Description
Dovecot 2.4 changes the auth driver from the shadow file to the PAM database. When using Imunify360, it is automatically added as a driver to the Dovecot configuration. This error does not prevent Dovecot from starting.
We've opened an internal case, CPANEL-50632, for our development team to investigate this further. Follow this article to receive an email notification when a solution is published in the product.
Workaround
Run the following:
