JRun 2.3.1 JSP 0.92 exception trace

[David Wall]

I'm running JRun 2.3.1 build 145 on Linux with Blackdown's 1.1.7v3 JRE and Apache 1.3.6.  Periodically, I see this exception.  It may be related to an error some people see coming to our site (I think it was a 550 complaining that it could not get a socket), but I've not seen this error myself.  I'm particularly worried since I can't determine if this is people hitting the stop button on a page load or whether there's some other resource limit I'm bumping up against.  I know that the free JRun only allows 5 concurrent servlet threads, for example.   Any thoughts out there?  Does anybody know if Allaire has setup a JRun group like Livesoftware had?
