A few observations:

I ran Seamonkey under eCS for a whole day on two different days without
difficulty.

Under Warp 4, at least once a day the program disappears. The following
appears in the popup log:

In Config.sys for eCS, I have a statement:

VIRTUALADDRESSLIMIT=1536.

In Config.sys for Warp 4 there is no VIRTUALADDRESSLIMIT= statement.

I will go ahead and add VIRTUALADDRESSLIMIT=1536 to the Config.sys for
Warp 4 and see what happens (unless you think that is a mistake).

Thanks,
Sandy

In a 32-bit OS like eCS/OS2 the maximal linear address space available to
an application is 4GB.  For various reasons, the usable address space will
be less.  Some of the address space will reserved for the kernel; some may
be reserved by video hardware; some may be unavailable because the kernel
simply does not make is available (i.e. VIRTUALADDRESSLIMIT).  In addition
not all applications are capable of using the all of the address space
that may be available.  For example,  Peter's enhanced Mozilla app builds
can use more of the available address space than the traditional builds.

  

and if that is the 
problem, is there anything I can do about it?
    

First you need to be sure this is the problem.  After this, you need to
tune your system to maximize the available address and maximize the use of
the available address space while minimizing negative side-effects. 
Tuning is always a balancing act.
