I found some info pointing at restarting hp-snmp-agents.
This is a machine with iLO, but not iLO2 as stated for this known problem, and I dont find any hp-snmp-agents to restart on the host.
Any one know that this might be... what can I do to stop it? I am on the custom HP ESXi 5.5 U2 build

Hello,
as I am aware this was caused by iLO/management agent combinaton - can you try updating both on a test host preferrably?
I did update everything but still got the same message. As I said, I could not even find any hp-snmp-agents to restart as stated by HP.

There is a KB that addresses this exact issue for a HP Host:
VMware KB: The vmkernel logs report a warning containing LinChar and LinuxCharWrite
Same here on BL460cG8, with latest updates
ESXi 5.5 Update3 3568722
HPE driver bundles hpe-driver-bundle-550.9.5.0
HPE ESXi 5.5 Managnet bundle 2.5.0-19
iLO 2.40
I have the same bug with my DL580 Gen8.
But HPE thinks, is not a bug, it's feature (!?!)

HPE CUSTOMER ADVISORY - Document ID: c05169530
These failed write messages occur when an application/service writes to the iLO 4 channel driver without adequate free channels available in iLO 4 to accept the write request.
These messages can be safely ignored as subsequent writes will be allowed once channels become open.
