[Dxspider-support] Latest source of utter frustration

[Michael Carper, Ph.D.]

Interesting.

I was 1-click away from putting it on a VM with 10x more memory today. In
the lowest point of the day, there were 500 users connected.

So there is no parameter that I can change to allow for more users? It's
running out of memory?

(NOTE: One thing I do know is that some users are logging in with the same
user ID from multiple sessions... each time they begin their new session
with "sh/dx 100" (or sh/mydx 100). As Dirk has explained this to me
previously, this puts quite a load on the node. These sessions ping-pong,
tossing each other off and reloading the spots. In Ham Radio Deluxe, I have
a change planned to deal with that. But I know this happens today.)
