            Bug ID: 264532
           Summary: sysutils/py-salt: OSError: [Errno 12] Cannot allocate
                    memory (originated from sysctlbyname('vfs.bufspace'))
           Product: Ports & Packages

Host is running CURRENT (FreeBSD 14.0-CURRENT #10 master-n256043-ce2525c8108:
Wed Jun  8 10:07:29 CEST 2022 amd64), the jail in question is hosted on this
box and also running the very same OS basis.

A jail is operatin as salt-master and salt-master, based upon standard python
3.8, is failing to start with the error shown beelow. The incident happened a
couple of days ago and out of the blue.

Version of salstack:
py38-salt-3004.1_1             sysutils/py-salt

The hosts's vfs.bufspace: ist set to 

vfs.bufspace: 28229632

I have no idea whether this is an error/bug related to lang/python38 or
sysutils/py-salt, or soemthing to be adapted due to changes in the underlying
OS (CURRENT). I left the settings of the main OS to its default value so far
and hope someone could give a hint how to fix this.

Thanks,

oh
