In that environment the only time I've seen a Java program have memory problems is one of mine that loads potentially very large documents into a PostgreSQL DB. It pulls in a lot of library code too, including JavaMail, Mstor and the JDBC code needed to talk to PostgreSQL. In all cases failures due to running out of memory were the result of exceeding the -Xmm defined memory space, i.e. nothing to do with JVM or code size because every time that happened, the run was successful after I'd increased -Xmm. IIRC that box had around 500MB of RAM. Since moving it to a 64-bit system with 4GB RAM and explicitly setting - xmm in the shell script that launches it I haven't hit and OOM problems with it. This issue is no worse than running a large C++ program with dynamically loaded library code. In fact it might well be better since the JVM uses a JIT compiler to recompile frequently used Java classes to native code and, presumably, discards the P-code as soon as its been replaced by native code. Similarly, a Swing-based roster editor I wrote to support a club I belong to only occupies 1.3 MB of RAM with a little 4777 duty slots assigned: that's the complete roster of weekend duties over a six month season with 14 duty assignments on each rostered day. So, bottom line: I've developed and run fairly substantial Java programs on relatively small Linux boxes and never had issues with running out of memory. -- -- Martin | martin at Gregorie | gregorie dot org
