[Glass] cannot allocate memory

[Otto Behrens via Glass]

Hi,

We call "System class >> performOnServer:" often from our seaside
server sessions. We get an error "HostPerform failed; errno 12, Cannot
allocate memory".

This happens at the end of the day, while sessions have been running
all day, and have been quite busy.

It appears as if there is a memory leak in this function; I don't
really understand what memory it is trying to allocate here.

We're assuming the System class >> performOnServer: is the way in
GemStone to execute shell commands. Should we be using another way?

Any ideas?

Thanks
Otto

I attach a stack ouput with more details as an example.

In this example, we call pdftk to fill in the fields of a pdf document.
