Subject: Summary: BUGFIX: Assert during FD exhaustion.
X-Git-Tag: SQUID_3_0_PRE1~181
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=601af4c6707825332de95b0af08b7998773e5346;p=thirdparty%2Fsquid.git

Summary: BUGFIX: Assert during FD exhaustion.
Keywords:

During FD Exhaustion we put static (noncbdata) into the event queue. This patch allows non cbdata to be used without triggering a cbdata assert.
