Hi,
I’m working with Thomas, he left few minutes ago (he is coming back on wednesday).
We still have the issue and no idea about the causes.
ESI Gate 5.1 + esigate.properties
Thx,
Emilie Poupon Adam

Objet : Re: [EsiGate-users] Connection thread leak
Hi,
In order to help me understand your issue, could you give more information: Which version of EsiGate are you using? Could you share your esigate.properties configuration file?
Please subscribe to the mailing so that your future messages will be forwarded directly without requiring an administrator to validate them.

Hi,
I’m experimenting issues with the ESI clientPool.
At some point (I can’t figure out what are the causes), threads start to grow until reaching the thread pool saturation.
The leaks happens linearly when requesting a healthcheck url, and any other request accelerates the behavior.
The following threaddump extract shows it hangs while acquiring the http client.
