Description

Running ClamAV causes sporadic kernel panics and resets with the following syntax:

panic: sbsndptr: sockbuf 0xfffff8006b399878 and mbuf 0xfffff800635b2900 clashing

textdump traces approx. 20 c-icap commands as such:

Reviewing ID's, the clashing buffer address ranges fall within c-icap
sockbuf 0xfffff8006b399878

101218                   S       select   0xfffff8006b35a1c0 c-icap

mbuf 0xfffff800635b2900
100805                   S       uwait    0xfffff800636d6180 c-icap

After one day, persistent boot loops until ClamAV is disabled. With ClamAV disabled, kernel panics cease and it resumes normal function
