Hi, A while ago I sent an email regarding these "*ETOOMANYREFS* Too many references: cannot splice." that we've seen since Debian updated the Jessie kernel to 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt20-1+deb8u3 (2016-01-17) x86_64 while older kernels, like 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u6 (2015-11-09) x86_64 showed no errors at all. I was wondering if no one else is getting these errors, or if you know any workarounds that might probe useful, apart from downgrading the kernel. I would say that the infrastructure we're running is quite standard, with directors balancing users to NFS backed dovecot servers. Best regards, Luis Ugalde.
Hi, Could you please have a look at https://lkml.org/lkml/2016/2/2/538 and see if this makes any sense to you? I've been checking kernel changes between linux_3.16.7 and linux_3.16.36, and this has popped out. Could this be the reason for the "too many references" errors? Regards, Luis Ugalde.
