Hi everybody. I'm running Eclipse, a Java IDE that seems to consume
a lot of memory, using Linux emulation under NetBSD 1.6ZK. The
JVM is crashing due to a SIGSEGV (I've attached the JVM crash trace
below).
My suspicion was that this happened because of a difference between
NetBSD and Linux behaviour when an application runs out of memory
NetBSD's expected behaviour, as according to our man pages for
getrlimit(2), has the process being sent a SIGSEGV. But Linux's
getrlimit pages say that exceeding the data segment size will cause
brk()/sbrk() to return 0 -- SIGSEGVs are signalled when there's a
stack overflow.
But more testing (just allocating new objects without releasing
them) doesn't seem to bear that out. (Using the attached testing
program, I always receive OutOfMemory exceptions)
Any ideas?
Brian.
I have the following suse_* packages from pkgsrc:
suse_x11-7.3nb2 Linux compatibility package for X11 binaries
suse_compat-7.3 Linux compatibility package with old shared libraries
suse_gtk-7.3 Linux compatibility package for GTK binaries
suse_base-7.3nb4 Linux compatibility package
And I'm running the latest Sun JRE/JDK:
sun-jre14-2.3 Sun's Java(tm) 2 Runtime Environment 1.4.2
sun-jdk14-2.3 Sun's Java(tm) 2 SDK, Standard Edition 1.4.2
