Panic message: Missing errorhandling code in vfp_esi_end(), cache_esi_fetch.c

[Pablo Román]

Hey there. My varnish instance crashes frequently (several times a week)
with the following error:


Panic message: Missing errorhandling code in vfp_esi_end(),
cache_esi_fetch.c line 388:

varnish-3.0.2 revision 55e70a4)


According to https://www.varnish-cache.org/trac/ticket/1044, this issue
should have been fixed in 3.0.2. Any ideas?

Thanks,
