RE: [squid-users] Squid is crashing

Hi Blot,

Thanks for the prompt response, do you mean I have to modify the startup script of squid and start it with?

"gdb /usr/local/squid/sbin/squid -D"

Further I have run the core analysis for both files it is giving this

[root_at_hostal-squid cache]# gdb --core=core.3878

Hi Farooq,
For debugging purpose launch squid with gdb.

gdb
file <path>/squid
run <args>

and when squid crashes, type "bt full"
