Description

hi,

my phone (with linageos) is now up quite a long time (31 days) and i guess termux is running at least 7 days without interruption (sometimes it gets killed if if someone overdone the javascript stuff on a i am forced to open...). But now it looks like the the inter process communication of termux-clipboard-get has somehow hung. Normaly it dose not take more then 10 secounds to get the clipboard, but now i was still waiting for it a lot longer. Here is some output i can give from my perspective without knowing exactly what is happening behind:

-bash-4.4$ termux-clipboard-get 
^C
-bash-4.4$ strace termux-clipboard-get

Research direction

Start with the termux-clipboard-get command and reproduce the hang after prolonged uptime on the reported Android setup. Trace it with strace as shown in the report and determine where the inter-process communication stops; done means clipboard retrieval returns normally instead of waiting indefinitely.
