Panic message: Assert error in vmod_set(), vmod_cookie.c line 102

[f00bar]

Hello,

I just installed the cookie module with varnishd (varnish-3.0.4 revision 9f83e8f)

and when I do a simple:

sub vcl_recv {
cookie.parse(req.http.cookie);
}

This is what I get in the syslog:

Looks like a classic workspace overrun.

Please increase sess_workspace (default 64K, increase to 96K/128K) and see if the problem persists.

I'm closing this for now, please reopen if you are still seeing the problem.
