Cant run multiple editly render at once on linux: Caught error Error: write EPIPE

[matukaking]

editly 0.14.2 ubuntu 22.10x64 python 3.10.7 node 16.13.2

i have installed every dependencies and the single video rendering works just fine, but when im try to render multiple video at the same time i get this error after the second video.

xvfb-run: error: Xvfb failed to start

on my local pc (win 11) multiple video rendering works fine.

do you guys know what could be the problem?

UPDATE> Im using this command to start the process: xvfb-run --auto-servernum --server-num=1 editly --json ./datajson/${albumid}.json

i get this error:
