Hi Alex,
 Sorry about the quiet. We have been having a spot of trouble:
http://squidproxy.wordpress.com/2014/09/07/squid-cache-org-outage/
 and my replies direct to you have been bouncing.

As to your specific crashes. The traces are clearly showing it is the
ESI custom parser code exceeding the 64KB string length limit. In
hindsight it is obvious that whole pages of content are likely to hit
that limit and I am a little surprised it did not come up years ago.

To fix these will require refactoring ESI code to use the new SBuf
type capable of holding 256 MB of string data (and being even further
extensible if we need to).

As a workaround meanwhile you could try building Squid with the
libxml2 or libexpat parser libraries. They should not hit these string
limits.

Amos
