!!! OutOfMemoryError !!! in filter-media for XLSX files DSpace 8.0

[Manuela Ferreira]

Hello,

An OutOfMemoryError occurs during filter-media execution when processing ~150 MB XLSX files.  It seems that the error occurs while the system is attempting to extract the text from the files.

I have already enabled textextractor.use-temp-file = true and increased the Java (JVM) memory as shown below, but the issue persists.

Environment="JAVA_OPTS=-Xmx12096M -Xms6024M -XX:MaxMetaspaceSize=2024M -Dfile.encoding=UTF-8”

dspace.cfg filter-media configurations below

#### Media Filter / Format Filter plugins (through PluginService) ####
# Media/Format Filters help to full-text index content or
# perform automated format conversions

#Names of the enabled MediaFilter or FormatFilter plugins
filter.plugins = Text Extractor
filter.plugins = JPEG Thumbnail
filter.plugins = PDFBox JPEG Thumbnail


# [To enable Branded Preview]: uncomment and insert the following into the plugin list
#                Branded Preview JPEG, \

# [To enable ImageMagick Thumbnail]:
#    remove "JPEG Thumbnail" from the plugin list
#    uncomment and insert the following line into the plugin list
#                ImageMagick Image Thumbnail, ImageMagick PDF Thumbnail, \
# [To enable ImageMagick Video Thumbnails (requires both ImageMagick and ffmpeg installed)]:
#    uncomment and insert the following line into the plugin list
#                ImageMagick Video Thumbnail, \
#    NOTE: pay attention to the ImageMagick policies and reource limits in its policy.xml
#          configuration file. The limits may have to be increased if a "cache resources
#          exhausted" error is thrown.

I need help with this.
Thanks in advance

try setting the JAVA_OPTS in the

bin/dspace

script directly. Just to verify if the problem may belong to the
environment settings or not.
