Hi all,
we have recently started seeing the following lines in the logs after upgrading the EX4300 virtual switch chassis(4 members) to version 19.1R3.9:
May 14 10:58:06 EX4300 /kernel: Process (1818,pfex_junos) has exceeded 85% of RLIMIT_DATA: used 487324 KB Max 524288 KB
The line pops up periodically on the switch(in general a few times in an hour). Since the upgrade there have been no significant changes on the switch except port configuration changes(mostly VLAN membership, LACP configurations, ....).
Doing some additional work per this
document I attach the following output:

Memory utilization seems a bit high but this could be because the virtual chassis is about 80% full(correct me if I'm wrong). The switch itself works fine, there are no complaints that the connected servers are having any problems or lag issues. The only minor complaint is that the switch seems a bit slower when doing commit check and commit commands.
Is this something to worry about and investigate further or is this normal behavior on this Junos version?
