Hi,
We are having squid crash a few times and creating Watson dumps when
user clears cache. We do stop the squid ( using Terminate Process),
clean the cache and restart it. This happens on field and we don't have
much info. The crash however seems to point to the squid source.. We are
using Squid version 2.5 STABLE 9. Is this a known issue on this version?
It's a known issue on all versions that starting Squid without correct
cache directories is fatal.
Please:
* use a newer release from http://squid.acmeconsulting.it/
* do not manually erase cache files.
Squid performs cache data updates live on demand. Reverse proxy
accelerators are the only confirmed case needing cache deletion. If you
are using one such reverse-proxy I would suggest that a windows build
with its FD limits is not the best option.
* use "squid -z" to reconstruct cache directories before starting
squid if they are lost or erased.

I tried searching on the release notes for this version and also on
Squid version 2.6 release notes but couldn't find any reference to this.
Can anyone please help us out on what might be the cause and help
resolve it.
Details of the crash is as below:
