R visualization console shows PCRE JIT compilation errors claiming no more memory

[Q_Emilia]

Hi!

I have hosted Rserve on a Google Cloud VM instance with CentOS system. I have connected it to SAP Analytics Cloud successfully (TLS and all working), but I keep getting errors when trying to work with R visualizations.

The errors I tend to get are as follows:

Warning in grep("^[[:alpha:]]{2}_", x[1L], perl = TRUE) :PCRE JIT compilation error 'no more memory'

Warning in FUN(X[[i]], ...) : PCRE JIT compilation error 'no more memory'

Warning in strsplit(x, "\n[ \t\n]*\n", perl = TRUE) : PCRE JIT compilation error 'no more memory'

I have tried debugging this by also just disabling PCRE JIT compiler in Renviron but it didn't seem to work. I have found very little information on this error, basically nothing from Rstudio community or R documentation. I have noticed that more than a decade ago this error was prevalent in some php systems but nothing on R or SAC. I did also increase memory allocations/limits for Rserve but didn't seem to be the cause of this error.
