When you terminate the DIR, it should print a lsit of allocated memory blocks. These might help analyzing why this much meory is used. (This only works if your Bacula is linked with smartalloc.) In my experience, the DIR tends to need lots of memory, but doesn't track much of it in the smartalloc list. I *assume* that some libraries it uses need all this memory - the MySQL client libraries seem most likely to need lots and lots of memory. Unfortunately, I know of no way to track the memory usage except for using valgrind, which is not really an option in a production environment. But, in my experience, the memory is freed once no jobs run. For reference: I run a server with 128 MB of RAM (IIRC) plus about 512 MB swap and that does five jobs in parallel. When I keep these jobs waiting for a long time (for example, because the need new volumes) I can crash the machine because the memory runs out. On a clients system, for example, there are 512 (+swap) MB, and running 10-15 jobs in parallel works fine, but >30 jobs result in the kernel running out of memory, too. The memory is used even if the majority of the jobs are only waiting for the SD to becoma available. Short answer: If you can debug this I'd be quite interested in your results. But you can easily work around the problem (if it is one for you) by stretching the schedules over a longer time. If you want to debug this, I'd recommend to use valgrind (perhaps strace can also help), but first see what the smartalloc report reveals.
