PHP, psexec does not output more than 4 kb to a file and freezes, how to fix it?

Question

PHP

Good afternoon friends, please help me solve one very important problem, through psexec I can’t output information to a file more than exactly 4 kb, i.e. 4096b, after outputting 4kb, the psexec process works, but no more information is added to the file, we waited about 30 minutes, no progress, if you just run psexec through cmd, then everything works fine, but problems arise through the php script.
As soon as they didn’t try both through exec and through system and through passthru, the result is always the same. you need to use exactly psexec so that the grep process starts on the server on which the information is being searched for
Thanks for the help

$psexec_in = psexec \\\\dr-server grep "log" D:\\true22\\ss2.txt > \\\\dr-server\\D$\\true.txt
