In May 2019 I added sleep(3) calls and removed them immediately afterwards - probably because the problem surfaced then and I tried to lower the write load, seemingly unsuccessfully. I am running this only every half a year or so. The problem certainly exist= ed on 12.3 and 12.4; I switched to stable/14 from 12.4. There does not seem to be a problem if the write load is rather small; but = if a substantial portion of consecutive stretches of ca. 20 GB needs to be rewri= tten the program will be killed. The machine in question has 16 GB main memory. -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
