I cannot open maestro or adexl views (IC 6.1.8)

My virtuoso locks for while (sometimes crashing) every time I try to open/create maestro or adexl views. ADE-L is working normally.

When it doesn't just crash, I get the following output at the CIW:

axlBeanstalkd process '29946' was stopped, the last strace information before it's stopped is dumped to '/tmp/strace_2025_12_03_13_42_48_29946'
Messages already created for current virtuoso session was lost and cannot be recovered.
*Error* error: Timed out attempting to connect to launched beanstalkd process. - nil

looking at /tmp/strace_2025_12_03_13_42_48_29946, I just get the redundant information:

[max@opa lp_working_dir]$ more /tmp/strace_2025_12_03_13_42_48_29946
strace: attach: ptrace(PTRACE_SEIZE, 29946): No such process

When virtuoso is invoked, the only exhibited warning is:

*WARNING* Connection to opa.ece.ttu.edu failed. No route to host

My checkSysConf returns the following results:
