@ali.moiaei don't know the reason but a clean build solved it maybe hash issue

@Bishwajit I redownloaded and rechecked the hashes, its OK for me, try a clean build and see if the issue persist or not, thanks

I ran a makepkg -g to get the keys. Working as intended.

system: 6.19.9-arch1-1 mongodb: v8.2.5

Issue(Core dumped): mongodb-bin package ships a systemd service file with the flag GLIBC_TUNABLES=glibc.pthread.rseq=0, which disables restartable sequences in glibc. but tcmalloc (Ubuntu compiled) bundled inside mongod requires rseq to work correctly — without it, memory gets corrupted after ~1 minute, causing the SEGV crash.

Solution: Override service file system {sudo systemctl edit mongodb} with {Environment="GLIBC_TUNABLES="}, this simply replace this line Environment="GLIBC_TUNABLES=glibc.pthread.rseq=0"

this worked for me

I've tried all combinations of settings, including enabling THP to no avail. I've had to roll back to 6.18 for now.

My mongo had crashed so many times my WiredTiger files were corrupted. A repair did the trick. I am employing the method that @openworldbtw43 mentions above.

sudo -u mongodb /usr/bin/mongod --config /etc/mongodb.conf --repair

Here's the most upstream issue: https://github.com/google/tcmalloc/issues/292 (it was determined that the issue is actually in tmalloc, not the kernel)

If you're experiencing MongoDB crashes on version 8.2.5-1 with recent kernels like 6.19.6, try this fix:

Edit /usr/lib/systemd/system/mongodb.service Change: Environment="GLIBC_TUNABLES=glibc.pthread.rseq=0" from 0 to 1

sudo systemctl daemon-reload sudo systemctl restart mongodb This enables restartable sequences support, which should resolve stability issues on modern Linux kernels.

@csatsias Thanks. My current combination mongodb-bin-8.2.5-1 and linux-6.19.6-arch1-1 is also healed by overriding the mentioned env.
