Memory is accumulating over time, eventually making some jobs fail with error
java.lang.OutOfMemoryError: Java heap space

I suspect it is connected to SSH pipeline steps plugin.
Each jobs use this plugin several times and sometimes receives back very long logs.

I attach a graphic of the memory accumulating over the months, while the number and quality of builds remained stable and a heap dump.

I am not an expert of Java so plese guide me if you need something else.

Thanks
