Hello,

I got following error when running some heavy queries
"ERROR: could not resize shared memory segment "/PostgreSQL.388782411" to
50438144 bytes: No space left on device SQL state: 53100"

I'm using a postgis 10 docker container with mounted volume on ubuntu 16
vps.

Some of failed queries can run after I increased my work_mem.

On the other hand, this issue is not producible on postgresql 9.6.

Hope to get any advice here.

Thanks and regards,

Thuc
