i.e that it could be other things which can produce the same problem.

In no way was I doubting whats happening at your end, what I am seeing
appears to be the same without the large number of "file descriptors".

Sure there is a lot more in the jserv.log, alas nothing more as far as of
value to the exception being raised other then
[13/04/1999 16:19:41:571 GMT] All data read.

[13/04/1999 16:19:41:579 GMT] Status: 500 Internal Server Error
[13/04/1999 16:19:41:579 GMT] Content-Type: text/html
[13/04/1999 16:19:41:581 GMT] javax.servlet.ServletException:
at Cdd_servlet.doPost(Cdd_servlet.java:350)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:521)
at javax.servlet.http.HttpServlet.service(HttpServlet.java:588)
at org.apache.jserv.JServConnection.run(JServConnection.java:359)
at java.lang.Thread.run(Thread.java:474)
Most importantly as I have the servlet working on one system (Solaris)
and the same class file fails on another (Irix), leads me to propose a
problem with Jserv - especially as the same servlet worked for many months
with Jserv 1.02b without any problems.
Any clues really appreciated.
