Objet : [SR-Users] : hight shared memory usage
Dear all,
I have 2 proxy running and we have a very big difference of memory usage between them, moreover we have more connected users on the proxy with less memory usage.
We have this issue on the first proxy, today we have to increase the shared memory as it was no more possible to setup new TCP connection.
We use the same version of the proxy, script is quite the same, one difference, on the proxy with the issue we increase the number of max TLS connection to 20K
Any idea ?
is TLS consuming more memory than TCP or UDP ?
BR
Laurent
First proxy (with high memory usage):
