That triggered a memory.  If you are using an older version of uniobjects in 
the .Net you can get memory issues when you upgrade the database.   Have a look 
at upgrading the uniobject .Net to the lastest release.

On unidata I have had to process many an xml file outside of the DB as the 
memory just shoots right up

If you are using uniobjects then I presume you have .net or java at the front 
end and it is likely that these environments are better suited to 'handling' 
the xml and simply passing data arrays to the universe layer to work on.

In order to save connection time on Uniobjects API requests, I came up with an 
Api which could contain several XML requests into one,  Process each one in the 
requested order and return the answer of each request in the resulting XML 

On Universe 10.2.11,  the API runs anywhere from 10 to 50 requests in a batch 
like this taking no more than between 45 and 59 megs of ram on a HP-UX server.

Starting with Universe 11.1.3, doing far fewer requests  (ei from 5 to 9) the 
memory requirements go up as high as 100 to 122 megs of Ram on a HP-UX. 
Somewhere it looks like Universe's XML generation routines are gobbling up 
memory and this memory is not getting freed.     It seems that many memory 
leaks were fixed from 10.2.1 to 11.1.3 according to the release notes but a 
huge new one was introduced.  

I know of the memory used by the process because I have a job which produce the 
output of the "top" command once a minute,  so the memory used by a process 
extracted from the output of the top command and logged.

Has anyone else experienced anything like this ?
