mongodb crashing...denied RWX mmap

[Robert Watson]

Updated my Arch Linux x86_64 server and now mongodb is crashing

System:

linux-grsec 1:4.7.4.r201609152234

mongodb 3.2.10

jdk8-openjdk 8.u112

Dec 05 16:20:05 server kernel: grsec: denied RWX mmap of <anonymous mapping> by /usr/bin/mongod[mongod:27399] uid/euid:113/113 gid/egid:113/113, parent /usr/lib/jvm/java-8-openjdk/jre/bin/java[java:22311] uid/euid:113/113 gid/egid:113/113

Dec 05 16:20:05 server systemd-coredump[27400]: Process 27381 (mongod) of user 113 dumped core.

-- Subject: Process 27381 (mongod) dumped core

-- Process 27381 (mongod) crashed and dumped core.

Any ideas to fix this? Thanks

Hi -

Is there any possibility that you can provide a stack trace from that core? That would help us see where the attempt to create a writable and executable page came from?

Also, how did you obtain this 3.2.10 version? Did you build it from source, obtain it from packages somewhere? If so, where? MongoDB does not make official binaries for Arch.

Thanks,

Andrew
