Multiple SIGSEGV's are occuring Many are near: system call: 26326: mprotect(0x800659000,4096,PROT_NONE) = 0 (0x0) 26326: SIGNAL 11 (SIGSEGV) Several others occurred: 26326: stat("/usr/local/openjdk8/jre/lib/jaxp.properties",0x7ffffebec078) ERR#2 'No such file or directory' 26326: SIGNAL 11 (SIGSEGV) A couple more near: 26326: madvise(0x8df4cb000,0xa0000,0x5,0xaaaaaaaaaaaaaaab,0x0,0x80100bbe0) = 0 (0x0) 26326: SIGNAL 11 (SIGSEGV) So something in the OpenJDK is having at least a problem with mprotect and madvise. These probably have POSIX and non-POSIX versions on FreeBSD. So problem is not 1 SIGSEGV but many.
