Opened: Jun 26, 2017

Severity: 4-Minor

Symptoms

devmgmtd exhausting file descriptors when state-mirroring peer-address is misconfigured: err devmgmtd[8301]: 015a0000:3: [evConnMgr.tcc:29 evIncomingConn] Incoming connection failed: Too many open files

Impact

devmgmtd has too many open files causing iControl issues as it is unable to communicate with devmgmtd.

Conditions

State-mirroring peer-address is misconfigured or configured to a self-ip with port lockdown misconfigured.

Workaround

Remove the stale or incorrect state-mirroring peer-address. Also check that stale and incorrect IPs aren't configured in: tmsh list sys db statemirror.peeripaddr tmsh list sys db statemirror.secondary.peeripaddr If they are reset that to default values, eg: tmsh modify sys db statemirror.peeripaddr reset-to-default Also check: tmsh list sys db trust.configupdatedone is true, and if not modify it so it is if the unit is part of a cluster. Restart devmgmtd after these changes: tmsh restart sys service devmgmtd
