sessions maybe dropped / how to view session count

[Simon Leary]

Hello shibboleth users,

I am trying to troubleshoot an issue where users are forced to sign in again with SSO, long before the session lifespan or timeout could be reached. Based on user feedback, it seems that this might be happening only when the SP is under heavy load. Is it possible that shibd has an upper limit on the number of sessions, which could cause older sessions to end early?

I would like to find out the number of sessions that are currently open. I discovered that there is a `https://localhost/Shibboleth.sso/Status` page, but it doesn't have much of any useful information. `shibd -h` doesn't show any relevant options. I also haven't been able to find any sign of sessions on the filesystem. I see in SAML Tracer that my session's "relay state" is prefixed with "ss:mem:", which tells me that my shibd is using the "memory storage service", so it makes sense that I didn't find anything. Am I missing something? Does anyone have tips or tricks that could help with this?

Thanks,
Simon
