I'm continously getting crashes with errcor code 1 and this message in the error log "There is insufficient memory for the Java Runtime Environment to continue." I'm playing mechanical mastery with a r5 2600, a rtx 3070 and 16 GB of ram, 7 of those allocated to mc in the curseforge settings. i tried reinstalling curseforge, reinstalling the modpack, running different modpacks, reinstalling java and reinstalling mc. does anyone have a guess what causes this?

Running out of memory is a common issue in Java applications, usually caused by inefficient memory management or not allocating enough memory for your program's needs. This can result in errors like "java.lang.OutOfMemoryError" being thrown. Here are some steps you can take to address this issue:
Increase Heap Size: Java applications run in a Java Virtual Machine (JVM), which has a default heap size. If your application requires more memory, you can increase the heap size using the -Xmx parameter when launching your application:
This example sets the maximum heap size to 2 GB. Adjust the value according to your application's requirements.
Optimize Memory Usage: Analyze your code for memory leaks and excessive memory usage. Make sure you're releasing resources properly, such as closing files, database connections, and freeing up memory when objects are no longer needed.
Use Efficient Data Structures: Choose appropriate data structures that minimize memory usage. For example, using ArrayList for large collections may consume more memory compared to more memory-efficient structures like HashSet or HashMap.
Profiling Tools: Use profiling tools like VisualVM, YourKit, or Java Mission Control to analyze memory usage and identify memory leaks. These tools can help you pinpoint areas in your code that are consuming excessive memory.
Garbage Collection Tuning: Adjust the garbage collection settings to better suit your application's needs. Different garbage collection algorithms and configurations can impact memory usage and application performance. You can use flags like -XX:+UseG1GC or -XX:+UseConcMarkSweepGC to choose different garbage collection algorithms.
Analyze Large Objects: If your application uses large objects (e.g., large arrays or collections), make sure they are being managed efficiently. Consider strategies like paging or streaming data instead of loading everything into memory at once.
Use Streaming: Instead of loading large data sets entirely into memory, consider using streaming techniques to process data in smaller chunks. Java provides various libraries for stream processing.
Externalizing Data: If your application deals with large data sets, consider externalizing the data to a database or file system rather than keeping it all in memory.
Profile and Optimize: Use a profiler to identify performance bottlenecks and memory-hungry parts of your code. Optimization can often lead to reduced memory usage.
Upgrade Libraries: Ensure you are using the latest versions of libraries and frameworks. Newer versions might include optimizations and bug fixes related to memory management.
Remember that tackling memory issues often requires a combination of strategies. Analyze your application's behavior, monitor memory usage, and iteratively make adjustments to improve memory efficiency.
