Expand / Collapse
Show/Hide Article Tools


This article applies to:

  • WebMarshal (versions 6.11 through 7.0)

Symptoms:

  • Error in Proxy log: Connection pool size of 6000 exceeded
  • Slow web page loading or failed loading
  • High resource usage on WebMarshal server 

Causes:

  • This issue can be caused when WebSocket connections are not released and never time out.
  • This issue has been observed more frequently in early 2018 and appears to be related to environmental changes on some third party servers hosting WebSocket services.

Resolution:

Upgrade to version 7.1 or above. This issue is resolved in 7.1 and later versions.

Workaround:

If you cannot upgrade immediately, you can apply a fix. This fix works with all supported WebMarshal versions (6.11 through 7.0). The "Connection Pool Size Exceeded Update" is available for download from the WebMarshal download page (login required).
