@pploegaert saw this in a maintenance process on his test env and IIRC I also saw this on a proxy on the nuvolat setup

still to be further investigated

seen again by @jeroenmaelbrancke @domsj After we changed the alba manager config on the global proxies (fragment cache) we see following logging: 2017-08-09 02:36:46 538539 -0400 - NY1SRV0001 - 6205/0000 - alba/proxy - 1271052 - info - Exception in alba_id_t: (Failure "attempting to use a resource from a pool which is being finalized")

@jeroenmaelbrancke also told me this kept on being logged, up to 247 times per minute

domsj commented 7 years ago

might be related to #777?
