[LAD] Jack error

Hello all, I get this error when starting any program using jack (1.9.22): BDB2034 unable to allocate memory for mutex; resize mutex region Cannot open DB environment: Cannot allocate memory This occurs only after the system and jackd have been running for a long time (weeks or months). Restarting jackd doesn't help, a reboot is required. I assume this is related to jackd using a Berkeley Database to store optional application and port data. I don't need this functionality, but there seems to be no option to disable it. Also it seems that BDB is no longer maintained. Any hints as to how to avoid this problem ? Ciao, -- FA
