shell error >>> "terminate called after throwing an instance of 'std::length_error' what(): basic_string::_M_create"

[richardhj]

On one host, I receive the following error(s), wondering why?

task cachetool:clear:opcache
  [remote] run . /home/xxx/html/shared/.env.local; if [ -f /home/xxx/html/releases/207/cachetool.phar ]; then echo +accurate; fi
  [remote] terminate called after throwing an instance of 'std::length_error'
  [remote]   what():  basic_string::_M_create
  [remote]  error  in cachetool.php on line 63:
  [remote] exit code -1 (Unknown error)
ERROR: Task cachetool:clear:opcache failed!

task deploy:symlink
  [remote] run . /home/xxx/html/shared/.env.local; (man mv 2>&1 || mv -h 2>&1 || mv --help 2>&1) | grep -- --no-target-directory || true
  [remote] terminate called after throwing an instance of 'std::length_error'
  [remote]   what():  basic_string::_M_create
  [remote]  error  in symlink.php on line 7:
  [remote] exit code -1 (Unknown error)
ERROR: Task deploy:symlink failed!

As you can see, the error occurs on different shell commands / tasks.
What is it about? Thanks!
