Too many references: cannot splice
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.

Hi,
I've been running the patched version for the last few days, and I can confirm that I have not seen any errors. I still have to check it with 4.x kernels, but it's working as expected with the current Debian Stable one.
