Assert error in vfp_esi_bytes_gg()

[Daniel Baker]

Hello, all.

We're running varnish 3.0.2 out of FreeBSD ports and are seeing the same crash on multiple different servers assert error in vfp_esi_bytes_gg on multiple servers:

Dec 12 03:09:24 bilee varnishd[1967]: Child (2372) Panic message: Assert error in vfp_esi_bytes_gg(), cache_esi_fetch.c line 273:   Condition(i >= VGZ_OK) not true. thread = (cache-worker) ident = FreeBSD,8.2-STABLE,amd64,-smalloc,-smalloc,-hclassic,kqueue
Dec 13 18:17:35 rokit varnishd[6636]: Child (6637) Panic message: Assert error in vfp_esi_bytes_gg(), cache_esi_fetch.c line 273:   Condition(i >= VGZ_OK) not true. thread = (cache-worker) ident = FreeBSD,8.2-STABLE,amd64,-smalloc,-smalloc,-hclassic,kqueue

Despite the error, it does not look like we actually got the core dumps.

It looks like there have been some possibly related commits in the last few weeks although the commit msg doesn't seem to reflect addressing a specific issue.  Has anyone else seen this in 3.0.2 and/or HEAD?

Thanks,

Daniel
