Sandra,

If it's only happening with one JSP, and it happens every time it's request=
ed, it's almost certainly a coding problem. Without looking at the source c=
ode, it's pretty hard to say what's causing it. From my own experience, I h=
ave seen only two coding errors that "hang" Tomcat. The first is opening da=
tabase connections from a pool and not closing them. The second is a page t=
hat forwards to itself somehow. Also look for code that creates an endless =
loop of some kind, although these usually either run out of memory, cause a=
n overflow, or time out.
