Avast is using SYSV SHM. One solution is that it should be using POSIX SHM which will generally have much less restriction upon the available memory (defaults to half of the available RAM). This isn't a grave bug BTW, it's just a configuration detail. In most cases, 32MIB is more than plenty, and Avast failing when it runs out is a bug in Avast. It's quite likely that this is due to a design flaw in Avast in general by having unrealistic expectations and failing to cope when these aren't met. What on earth does it need all that shared memory for that couldn't be shared by either 1) having it as a file on disc that all processes can open and map in 2) forking and inheriting the parent's data 3) using POSIX SHM ?
