What does OSError Errno 22 mean?
It means an operating-system call received an invalid argument. The exact cause depends on the operation and platform, so inspect the traceback and the values passed to that call.

Should I catch OSError and ignore errno 22?
No. Catch the specific case only when you have a documented repair. Ignoring it can hide invalid paths, modes, closed handles, or other data-loss risks.

How do I identify errno 22 in code?
Compare the exception's errno attribute with errno.EINVAL, then inspect the exact call and its arguments. Other OSError values may indicate permissions, missing files, or disk failures.

Built-in Exceptions — Python 3.14.7 documentation
The tuple of arguments given to the exception constructor. Some built-in exceptions (like OSError) expect a certain number of arguments and assign a special meaning to the elements of this tuple, while others are usually called only with a single string giving an error message.

5. Built-in Exceptions — Python 3.3.7 documentation
This exception is raised when a system function returns a system-related error, including I/O failures such as “file not found” or “disk full” (not for illegal argument types or other incidental errors). Often a subclass of OSError will actually be raised as described in OS exceptions below.

For clarity, and because some error numbers can differ between platforms (see e.g. this comparison), I would recommend using the errno module in order to catch the specific type of OSError in a cross-platform way:
import errno
try:
# Code that might fail...
except OSError as e:
if e.errno == errno.ENOMEM:
# Handle ENOMEM case...
else:
raise
You can use the dictionary errno.errorcode to find the name of a specific error code in the errno module:
>>> errno.errorcode[12]
'ENOMEM'
Note that error number 12 specifically seems to be the same across most platforms, but many others differ.

You can use the errno attribute of the OSError. For an error:
>>> raise OSError(12, 'Some Error')
Traceback (most recent call last):
File "<ipython-input-5-8a046f16ebb6>", line 1, in <module>
raise OSError(12, 'Some Error')
OSError: [Errno 12] Some Error
Use the following:
try:
raise OSError(12, 'Some Error')
except OSError as e:
if e.errno == 12:
print('OSError no. 12 caught')
else:
raise
# Output:
# OSError: [Errno 12] Some Error
