My system generated crash report (including a core dump) that identified a segfault in the Java runtime. A Java process is started by JGR(). JavaGD() seems to start another Java process The OP's log starts with segfaults (signal 11) in a Java process: Sep 9 08:51:12 localhost audit[53948]: ANOM_ABEND auid=1000 uid=1000 gid=1000 ses=2 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=53948 comm="Thread-5" exe="/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.265.b01-1.fc32.x86_64/jre/bin/java" sig=11 res=1 Sep 9 08:51:12 localhost kernel: audit: type=1701 audit(1599659472.313:4973): auid=1000 uid=1000 gid=1000 ses=2 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=53948 comm="Thread-5" exe="/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.265.b01-1.fc32.x86_64/jre/bin/java" sig=11 res=1 The system log > showed that a crash occurred in Rf_eval (libR.so + 0x157ab3); i.e., in > the R library.
